Abstract

A method and apparatus determines an identity of at least each card in a card hand at a casino table card game. The method is performed automatically by a computer-based system that reads the rank and suit of each card that leaves a dealing shoe and then uses a smart discard tray that reads the discards as they are taken from the table. It is optional and preferred to provide a signal to the computer of the presence of at least one card in the dealer'"'"'s hand. Additional cards are dealt to hands. Exhausted hands are removed from the table and placed into a discard rack. Each card in each exhausted hand is read when placed in the discard rack to determine rank and suit of each placed card, and the computer reconciles cards placed in the discard rack with cards that left the dealing shoe.

Claims

1. A method of determining an identity of at least each card in card hands at a casino table card game comprising:

automatically reading the rank and suit of each card that leaves a dealing shoe;

dealing hands according to rules of play of the casino table card game with at least one hand comprising at least one card being dealt to a player;

defining an edge of the at least one hand by the read rank and suit of the at least one card dealt to the player;

dealing additional cards to the hands according to the rules of the casino table card game;

providing a signal of at least one of a completion of a hand, a completion of initial hands or completion of first cards having been dealt to all players present at the table by manual activation of a signal by a dealer or automatic signaling resulting from sensing of a card at a signal position;

removing exhausted hands from the table and placing the exhausted hands in a discard rack;

reading each card placed in the discard rack from the exhausted hands to determine rank and suit of each card placed in the discard rack; and

reconciling the cards placed in the discard rack with the cards that left the dealing shoe.

2. The method of claim 1 wherein in addition to the at least one hand being dealt to the player, a hand is dealt to the dealer or to a common card area, and automatic signaling results from sensing of a card at a signal position comprising the common card area or a position where dealer'"'"'s cards are placed.

3. The method of claim 2 wherein the first card, an initial hand or the complete hand is dealt to the dealer and the signal of the completion of hands comprises signaling that a first card, the initial hand or complete hand has been provided to the dealer.

4. The method of claim 2 wherein there are multiple players and each of the mutliple players receives an at least one card, and the signal is provided when a) a first dealer card, the initial hand or dealer'"'"'s complete hand is received or b) at least a common card is received in the common card area.

5. The method of claim 4 wherein the signal is provided that the first dealer'"'"'s card or the dealer'"'"'s initial hand has been provided to the dealer.

6. The method of claim 5 wherein a number of active player positions is determined by a count of a number of cards that leave the dealing shoe before the first dealer card or first common card is signaled.

7. The method of claim 5 wherein complete hands of a specific number of cards are sequentially dealt to players and a number of active player positions is determined by a count of the number of cards dealt divided by the number of cards before the signal of the presence of at least one card in the dealers hand or the common card(s) is made.

8. The method of claim 5 wherein the casino table card game is blackjack and cards are dealt to each player position and a dealer position one at a time.

9. The method of claim 8 wherein exhausted hands placed in the discard rack are reconciled with known hands, the known hands based at least on knowledge of a set of first two cards wherein each card of the at least two cards has left a dealing shoe and was automatically read for its rank and suit and then was received in a hand that became an exhausted hand and the exhausted hand was placed in the discard rack.

10. The method of claim 4 wherein a number of active player positions is determined by a count of a number of cards that leave the dealing shoe before the first dealer card or first common card is signaled, and edges of each player hand are defined by the read rank and suit of the at least one card received by the player.

11. The method of claim 4 wherein complete hands of a specific number of cards are sequentially dealt to players and a determined number of active player positions is determined by a count of an initial number of cards dealt divided by the initial number of cards per hand before the signal of the presence of at least one card in the dealers hand or common cards is made.

12. The method of claim 11 wherein the casino table card game is blackjack and cards are dealt to each player position and a dealer position one at a time.

13. The method of claim 4 wherein the casino table card game is blackjack and cards are dealt to each player position and a dealer position one at a time.

14. The method of claim 13 wherein a signal of the presence of a dealer'"'"'s initial hand is used to determine a number of active player positions.

15. The method of claim 13 wherein exhausted hands placed in the discard rack are reconciled with hands that have automatically had their rank and suit read as each card left the dealing shoe;

and then were dealt as hands according to the rules of play and based at least on knowledge of a set of first two cards received in a hand placed in the discard rack.

16. The method of claim 4 wherein a signal of the presence of a dealer'"'"'s initial hand is used to determine a number of active player positions.

17. The method of claim 4 wherein a first number of complete hands of a specific number of cards are sequentially dealt to players and a determined number of active player positions is determined by a count of a second number of cards dealt divided by an actual number of cards dealt before the signal of the presence of at least one card in the dealers hand or the common cards is made.

18. The method of claim 1 wherein a number of active player positions is determined by a count of a number of cards that leave the dealing shoe before a first dealer card, dealer initial hand, a first common card or complete set of common cards is signaled.

19. The method of claim 18 wherein all active player positions are determined and after determination of all active player positions, initial hands for each player position are determined as known hands.

20. The method of claim 18 wherein the casino table card game is blackjack and cards are dealt to each player position and a dealer position one at a time.

21. The method of claim 20 wherein a signal of the presence of a dealer'"'"'s initial hand is used to determine a number of active player positions.

22. The method of claim 20 wherein all active player positions are determined and after determination of all active player positions, initial hands for each player position are determined as known hands.

23. The method of claim 20 wherein exhausted hands placed in the discard rack are reconciled with hands that have automatically had their rank and suit read as each card left the dealing shoe;

and then were dealt as hands according to the rules of play and based at least on knowledge of a set of first two cards received in a hand placed in the discard rack.

24. The method of claim 20 wherein exhausted hands placed in the discard rack are reconciled with hands that have automatically had their rank and suit read as each card left the dealing shoe;

and then were dealt as hands according to the rules of play and based at least on knowledge of a set of first two cards received in a hand placed in the discard rack.

25. The method of claim 1 wherein exhausted hands placed in the discard rack are reconciled with hands that have automatically had their rank and suit read as each card left the dealing shoe;

and then were dealt as hands according to the rules of play and based at least on knowledge of a set of first two cards received in a hand placed in the discard rack.

26. The method of claim 1 wherein exhausted hands placed in the discard rack are reconciled with hands that have automatically had their rank and suit read as each card left the dealing shoe;

and then were dealt as hands according to the rules of play and based at least on knowledge of a set of first two cards received in a hand placed in the discard rack.

27. A system for determination of at least individual hands of cards in a casino table card game comprising:

a card delivery device that reads the rank and suit of first cards delivered to a player hand position and/or a dealer hand position, and sends first signals of the suit and rank of each card to a processor,

the processor identifying the rank and suit of the first cards delivered to a player hand position as an edge of a hand;
